The surface roughness of a road may significantly affect the behaviour of a vehicle and the driver. Merely being able to describe road roughness is not enough; it is necessary to establish a correlation between the measured roughness of a road surface and the penalties imposed on the driver-vehicle system as a consequence of using the rough road. This investigation shows the effects of road roughness on the behavior of vehicle and driver system in terms of the following factors: the vertical driver acceleration, lateral tire forces (for study of vehicle handling characteristics) and the normal tire forces (acting between the road surfaces and the tyre). By establishing acceptable levels for these quantities it is possible to set limits for road roughness.(a) for covering abstract of the conference see IRRD abstract no. 243280. (TRRL)
